1 Claim.

Our invention refers to agitator mixers for paint or like liquids, whichliquids have a tendency to settle in a container, resulting in aseparation of the heavy or dense body at the bottom and a light or thintop portion.

The primary object of our invention is to provide a simple and effectiveagitator wherein a top blade rotates upon a single plane, associatedwith a bottom floating blade, which blade churns or agitates the thickbottom liquid and said blade gradually sinks as the density of theliquid is lightened, whereby the paint is uniformly mixed, ready foruse, it being understood that various liquid beverages may be treated inthe same manner.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claim, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

In the drawings:

Fig. 1 represents a side elevation of an agitator embodying the featuresof our invention, with parts broken away and in section to more clearlyillustrate structural features, the same being shown associated with acontainer illustrated in dotted lines.

Fig. 2 is a sectional plan view of the same, the section being indicatedby line 2-2 of Fig. 1; and

Fig. 3 is another detail plan sectional view, the section beingindicated by line 33 of Fig. 1.

Referring by characters to the drawings, l indicates a flanged capadapted to be seated upon the mouth of a can A, illustrated in dottedlines of Fig. 1, or other suitable container. The cap has securedthereto a depending yoke 2, the bottom stretch of which yoke is formedwith a journal bearing 2'.

The cap I is also provided with a central journal bearing I, and mountedin said bearings is a shaft 3, to the upper end of which shaft may beattached either a motor or a manually actuated crank connection (notshown).

Secured to the shaft 3-, between the cap and yoke journals, is a doublespiral blade 4, the upper and lower ends of which are formed withcollars 55, which collars are secured to the shaft.

The bottom end of the shaft 3 extends a predetermined distance beyondthe bottom stretch of the yoke 2, and secured to this extension is apair of looped arms 6-6, the upper and lower connected ends of whicharms are provided with collars 6-6, which collars are secured to theshaft.

Slidably mounted upon the shaft extension is a hubbed blade 1 and, asshown in Fig. 2 of the drawing, the wings of the blade are engaged bythe looped arms 66, whereby, upon rotation of the shaft in the directionof the arrow, the bottom blade is revolved, which blade, as shown inFig. 1 of the drawing, is floating upon the heavy bottom liquid paint,as indicated upon the line B, it being understood that the upper bladeserves to agitate the top layer of liquid, as indicated at the line C,which lighter liquid separates from the heavier portion when thecontainer or can is at rest.

From the foregoing description it is apparent, when power is applied tothe shaft, the lighter portion of the paint is thoroughly agitated orstirred by the upper spiral blades 4 and at the same time the lowerfloating blade 1, which is immersed into the thick bottom liquid, willgradually stir or agitate said bottom liquid to thoroughly mix the samewith the upper light liquid, and as said heavy liquid is graduallydiffused or thinned out, the blade I will slowly slide downwardly to thebottom of a container, whereby the entire heavy portion of the paint isthoroughly mixed with the upper portion thereof, and the paint is readyfor use.

We claim:

A mixer for paint or like liquids having a cap adapted to seat upon acontainer; comprising a yoke extending downwardly from the capapproximately midway of a container, a shaft journaled in the cap andyoke terminating adjacent to the container bottom, a spiral bladecarried by the shaft extending between the cap and yoke journals of acomparative small diameter adapted to be submerged in the top lightliquid, a pair of longitudinally disposed looped arms secured toREFERENCES CITED the lower portion of the shaft below the yoke, Thefollowing references are of record in the and a radially disposedfloating blade slidably file of this patent: mounted upon the shaftbetween the arms, the 5 floating blade being initially adapted to settleUNITED STATES PATENTS upon the top thick surface of the bottom liquidNumber Name Date and to gradually sink therein as said bottom 205,859Hamble July 9, 1878 liquid is agitated by the floating blade to thus419,200 Kahlenberg Jan. 14, 1899 uniformly mix the thin and thickliquids. 10 1,740,709 Parker et a N 1366- 1926 ROLAND G.
